Aconite's Prophecy

The black hound. The white hound. The red dove. The blood moon. The fertile sea. The barren forest. The old crow. The new starling. The king of the crossroads. The mirror of snakes. The prison of iron—

Speculation
The hounds more than likely refer to The King, as they tend to. The red dove may refer to the boy Tressa Davies watches die in Infinity Mirror, commonly called the "mourning dove." The blood moon seems to reference a line in Episode Seven: King in the Labyrinth; "Have you ever seen a moon so red it makes your blood look white?" The fertile sea and barren forest don't have apparent canonical connections. The old crow may also be a reference to the King. The new starling is almost definitely a reference to Mabel Martin, who is referred to as a starling by Veratrine; "starling" is also the answer to a riddle referencing being caged, which Mabel is for a vast majority of the podcast. The king of the crossroads is either a reference to the King, to Anna Limón (the current King), or to Thomas, who is stuck in a form of "crossroad" due to his time loop. The mirror of snakes is probably Mabel and Luna Thorne, who share a mirror. The Court as a whole often refer to Mabel as a snake or snakeling. The prison of iron may be in regards to Aurora Silver's less-than-savory methods of gaining these prophecies, through the torture of young girls, specifically Ekaterina Roskova and Mabel Martin. Iron is also deadly to faeries, as shown when Mabel got shot and promptly nearly died in Episode Thirty-Two: Temporal Snake.
